ELECTRICAL CONNECTER.

Application filed May 17, 1927. Serial No. 192,043.

My invention relates to electric connecters.

The object of my invention is to provide a tight engaging contact.

A further object of my invention is to provide a locking means to prevent separation by vibration or longitudinal strain.

A still further object of my invention is to provide an insulation that is secured in place by the connecting members when properly placed in contact.

A still further object of my invention is to provide contacting members having a socket axially extending into the outer ends to rewire the cable, and in which the cable is soldcred.

These and other objects will hereinaftel e more fully explained.

Referring to the drawings:

Fig. 1 is an elevation of the socket member, partly in sect-ion.

Fig. 2 is an elevation of the dowel member, partly in section.

3 Fig. 3 is an illustration showing the conuecting members assembled, and the insulator placed thereon, the insulator being a longitudinal section.

Fig. 4 is a cross section taken along a line 4-4 in Fig. 3 looking in the direction of the arrows, in this-view is shown in tubular insulation as a modification.

Fig. 5 is a cross section through the cable, taken along line 55 in Fig. 3 looking in the direction of the arrows, in this view is shown a square form for the exterior of the insulator.

The mechanism herein disclosed consists of a socket member 1, and a dowel member 2. Both of said members have a flange 3 on the outer ends thereof. Axially positionedin said members and entering at the outer ends are sockets 4 in which the ends of the cables 5 are placed and secured by soldering, by which means a perfect contact is made between the cables and their respective contact members. i

In the opposite end of member 1 is a bore 6 in axial alignment with the socket in the opposite end. The said bore functions as a sleeve to receive the dowel 7 of member 2. In the side of the sleeve is a slot 8 adapted to receive a pin 9 which is rigidly and radially positioned in the dowel 7 as shown in Figs. 2 and 4:. The said slot extends longitudinally to the bottom of the sleeve as shown in Fig. 1, and will function as a flexible means when the dowel enters said sleeve.

Paralleling the slot and spaced therefrom is the said slot is connected to'the first said slot as at A, by which means the pin is free to rock into the second said slot, and when drawn outward the pocket is a means for locking the dowel against rotation, and also a means to prevent separation of the dowel and its respective sleeve.

In Fig. 3 is shown the pin 9 as it engages separate the electric connecterswhen drawn from each other.

\ The insulator 11 is bored axially to fit snugly on the members 1 and 2 between their respective flanges 3. The ends of the said insulator is bored a short distance to increase the diameter for free engagement of the endsthereof over said flanges. The depth of the increased portion of the bore is suflicient that their shoulders C will permit the, members 1 and 2 to snugly engage at shoulder B without binding the said insulator, and bein so arranged is securing means to prevent t e insulator from being removed until the connecters are separated. i

It is now readily seen how perfectly the metallic connectors are insulated from external contact, also the simplicity by which it is installed and maintained.

The invention herein disclosed may be applied to electric cables of any capacity and including terminals. The structures being so made are equally as simple to connect as an ordinary plug, except that the members rotate to a locking position. And the dowel fitting snugly in the sleeve insures a perfect contact as the sleeve tends to spring as the dowel enters.

Such modifications may be employed as lie within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In an electric connecter, a member having a bore entering at each end and separably terminating near the center, a flange on one end of the member, a slot longitudinally positioned in the bore of the op osite end of said member, a pocket spaced f om the slot cen-.

trally positioned and communicating with said slot, a second member having a bore axially positioned entering one end, a flange on the said end thereof, a dowel axially extending from the o posite end of said member, the dowel adapte to engage in the slotted bore of the first sa1d member, a in radially extending from the side of the owel to engage in the slot of the first mentioned member and adapted to rotate itno the pocket as locking means against longitudinal separation of said members, an electric current conductor to en age snugly in the bore of the flanged end 0 the first mentioned member, and an electric current conductor to enga e in'the bore of the second member, in com ination with an insulator having a bore to engage on said members, an increased diameter of the bore entering each end to receive the flanges of said members, substantially as shown.

2. Inan electric connecter, two connecting members of the kind described, having an outwardly extending flange on the one end of each thereof, a dowel on the opposite end of oneof said members, posite end of the other member to receive the dowel, a pin radially extending from the dowel, aslot and a pocket in the socket of the other member to receive the (fin as a locking means against rotation an withdrawal and a socket in the opb of the dowel, a hollow insulation member iii which the first mentioned members may be connected, a shoulder on each end of the insulator to engage between the flanges when the first mentioned members are locked together whereby the said insulation is not removable until the first said members are unlocked and withdrawn from each other, all as, and for the purpose described.

3. In an electric .connecter, a member having 'a split socket in one end thereof to receive a dowel, and a ocket positioned at one side of the split, an a socket in the opposite end, a cable in the last named socket integrally connected therewith by soldering, a member having a socket in one end, another cable in said socket integrally connected therewith by soldering, a dowel on the opposite end of said member to enter the dowel receiving socket of the first mentioned member, a pin in the side of the dowel to engage in the pocket of the socket to form locking means when the members are rotated in oppostie directions, a flange on the outer end of. each of said memers, and an insulator to engage on said munbers between the flanges and to extend over said flanges.

In testimony whereof I afiix my signature.

EDWARD H. BOONE.
